6. Maintenance

To maintain the clarity and effectiveness of your screen protector:

• Regularly wipe the screen with a soft, lint-free cloth to remove fingerprints and smudges.
• For stubborn marks, lightly dampen the cloth with water or a screen cleaning solution. Avoid harsh chemicals.
• Do not use abrasive materials or sharp objects on the screen protector, as this may damage its surface.

7. Troubleshooting

• Bubbles After Installation: Small bubbles often disappear within 24-48 hours. For larger bubbles, gently lift the nearest edge of the protector and reapply, pushing the bubble out with a soft cloth.
• White Edge Phenomenon: For some phone models, especially those with curved edges, a 'halo' or white edge may appear around the screen protector. This is a common issue with non-full cover protectors due to model design. Use the provided repair liquid by applying a small amount along the white edge to help it adhere and become less visible.

• No Camera Hole: Please note that some screen protectors, particularly the 'Non-full cover' variants, are designed to cover only the display area and may not have a specific cutout for the front camera. This design choice aims to maximize screen protection while maintaining compatibility with various phone models.

8. User Tips

• For optimal results, install the screen protector in a dust-free environment, such as a bathroom after a hot shower, to minimize airborne particles.
• If you experience persistent white edges or prefer a protector that covers the entire front screen, consider purchasing a 'full cover' screen protector if available for your specific model.
• The provided repair liquid is effective for addressing minor white edges. Apply sparingly and wipe off any excess.
